250 ROYAL SOCIETY OF CANADA 
majority are still in manuscript. During this time also, attempts were 
made by Professor Webber of Harvard College, who came to Passama- 
quoddy for the purpose, to determine the latitude and longitude of the 
mouth of the Magaguadavic and Scoodic, but owing to unfavourable 
weather the attempt was abandoned for the time, to be renewed with 
much better results the following year. Webber’s Report, given in 
full in the Boundary Ms., has not yet been published, though a docu- 
ment of considerable local interest. 
Finding, however, that the surveys could not be completed before 
the following summer and that little further progress could be made 
until they became available, the commission adjourned to meet in the 
following August at Boston. 
On the reassembling of the commission for their third meeting 
at Boston in 1797, the agents filed their respective arguments. That 
of the American agent is a lengthy folio volume with this title: “The 
Claim of the United States of America to the Magaquadavic as the 
St. Croix Boundary stated by their Agent, James Sullivan, 1797.” 
It was filed at Boston, August 16, 1797. This argument is laborious 
and involved, and in the all too familiar style of the special pleader, 
and it contains not a few erroneous and carelessly-worded statements. 
He tries to show that in 1782 His Majesty had no Province of Nova 
Scotia which had any connection with Alexander’s Grant of 1621, in- 
asmuch as all the country to the eastward of Massachusetts was 
granted to Massachusetts Bay in 1691 and no restriction of boundary 
was made until the treaty of 1782. The purport of this argument was 
to show that the St. Croix of the treaty of 1783 was not the St. Croix 
of Champlain, but a brand new St. Croix created by the treaty on 
the basis of Mitchell’s map of 1755, and that hence the question could 
be settled only by identifying the St. Croix of Mitchell’s map, which 
being the easternmost of the rivers emptying into Passamaquoddy Bay 
must be the Magaguadavic. He places much reliance upon the ex- 
pected testimony of the commissioners who negotiated the treaty, who 
were to testify that it was the easternmost river of Mitchell’s map which 
was to form the boundary.? He also advanced the claim, later with- 

1 The observations were made by himself aided by Thomas Wright. They 
made as their final result the latitude of the middle of the mouth of the 
Scoodic (near Joes Point), Lat. 45° 5 5” N. and Long. 67° 12’ 30” W. from Green- 
wich, (3° 54’ 15” E. from Cambridge). The latitude and longitude of the mid- 
dle of the mouth of the Magaguadavic was obtained not directly by observa- 
tion but by calculation from the Scoodic, and was, Lat. 45° 7’ 39” N. and Long. 
67° 1’ 0” W. from Greenwich (4° 5’ 45” E. from Cambridge). By a subsequent 
negotiation between the two governments (Moore, 23), it was decided to dis- 
pense with the requirement that the latitude and longitude of the sources 
should also be specified.
